Our goal was simple––make a collection of audio products that stay true to our DNA. Tough, after all, is in our name, and the audio collection gives people a product that works as hard as you do. Environmental noise exposure is one of the leading causes of hearing loss. In order to get the best possible noise reduction rating certification from the EPA, our buds were designed with an angled tube. Our cables were set to the same high standard, featuring extra-large gauge cable and reinforced with Kevlar that was tested over 10,000 times (industry standards is 5,000 cycles). The large proprietary controller box boasts positive feel buttons, a Halo 360 Microphone and EQ/Voice control to optimize sound for music or calls, giving you quality communication performance. All products in the Tough Tested Noise Reduction Audio collection have IP ratings to be water, sweat, and dust resistant. In short, these earbuds are made to go to work.
